How can Trump refute intelligence assessments?

Where does President Donald Trump get his intelligence information from that he can refute intelligence assessments from the heads of the foremost intelligence agencies in America?

There is no one at the cabinet level with any experience in the intelligence field who can provide him with the same information. The closest is Secretary of State Mike Pompeo, who served as director of the CIA very briefly and hardly enough time to develop any meaningful knowledge of the intelligence community. Further, he served in an Army infantry division as a captain, hardly noteworthy from the intelligence assessment standpoint.

Trump clearly does not have any idea of the process that bits of intelligence data undergo over and over to verify credibility before piecing them together to form a picture from which to arrive at a meaningful assessment. It's the "I probably know more than my Generals…" mindset. Out of touch doesn't begin to describe him. It's sad.
